Don't know if you are still working on this thread rhd but felt this is quite a practical piece of information if someone was to search for available diodes. Thorlabs has some 100mW 633nm diodes:
Good pricing on Avnet:
Buy USHIO OPTO SEMICONDUCTORS Laser Diode AIGaInP-LD 636nm 100mW 3-Pin #HL63163DG from Avnet Express.
I wonder if DTR can get these for us giving the Ushio diodes he already stocks.
